Edit:
The resetera users collige and , are batch upscaling Gamecube games, they already have Metroid Prime and Beautiful Joe in record tme, I think in something like a week, Im speechless, so maybe zelda can be batch upscaled.

Two questions, apologies if these have already been addressed (I haven't read this entire thread)

The video and screenshots by Nerrel show the game in true 16:9, while I find setting 16:9 in GlideN64 simply horizontally stretches the video. How do you get this true 16:9?

Has there been any effort with 30 or 60 FPS hacks? As linked in the description of Nerrel's project overview video, there has been quite an effort to get 30 FPS in MM on Dolphin. However I haven't found any such hacks/codes get higher framerates working in N64 MM.

I use the "adjust option," which seems to work really well aside from a few effects being visibly culled on the edges. Nobody seems to be interested in making a 30fps code for Pj64; at least, not when I asked about it a while ago. If you want to request one you can try in one of the 60fps threads, it might help to have more demand: http://forum.pj64-emu.com/forumdisplay.php?f=12

Personally when I play this game, I don't really notice the low FPS much. I think it's usually more noticeable when you have free-cam movement. Also I think the animations in this game might still play at 25 FPS if you managed to get it running at a higher framerate. So even if you did get it running faster, animations would stick out a lot if that's true.

A simple solution for now, I'd say, is to maybe use a TV with Motion Smoothing. Drawbacks are the input lag and the artefacts it can introduce at high speeds. If your TV is good enough then the input lag will be minimal (I was able to get a super solid experience playing Spyro Reignited (Xbox One version) on my TV with this setting enabled) and most of the time the artefacts will be out of your focus so they're not all that noticeable. It depends on the TV really, as they typically do have some unplayable input lag with this setting turned on; for me it does seem worse when having it used on a PC video input rather than the Xbox video input... though that might be due to it outputting in 4K and making the TV have to process a bigger image. Perhaps the newer and more expensive your TV is, the better it handles it? Might depend on the brand too.

Here's the first half of the bay. Sorry if anyone is disappointed by the lack of screenshots lately, but for this area it's better to see things in motion with all of the water and scrolling light effects:
